RALEIGH, N.C. (AP) — A Waffle House waitress has received a $1,000 Mother’s Day tip directly from her customer after the restaurant refused to give it to her because it was left on a credit card.

Shaina Brown was working the night shift in Raleigh when a man left her the tip. But the Waffle House tells The Raleigh News & Observer that it refunds large tips unless they’re paid by cash or check to avoid disputes about charges.

Brown tells WTVD-TV in Raleigh she was humiliated when the restaurant refused to give her the money.

She says she got a call last week from her customer, who wants to remain anonymous. She says he had heard about her problems and wrote her a check directly.
